IMPROVEMENT IN CAR-AXLE BOXES.

Specification forming part of Letters Patent No. 156,767, dated November10, 1874; application filed September 16,1874.

CASE 0.

To all whom it may concern:

Be it known that I, JOHN M. BROSIUS, of Richmond, in the county ofHenrico and State of Virginia, have invented a new and Improved Oar-AxleBox and Lubricator; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawing, forming a part of this specification, inwhich- Figure l is a longitudinal sectional elevation Figs. 2 and 3,front and rear end views, and Fig. 4 a cross-section in detail.

The invention relates generally to the axleboxes of car-trucks; andconsists in several improvements, which will first be fully described,and then pointed out in the claims.

A represents a car-axle box, and B the journal that works therein.

First, I make the journal-gate E with excisions e e at the lower end,and place in the guidegroove E the triangular blocks or inclined strips0 6. By this construction the gate does not require to be held byhandwedge or other device, but will restin position until the journal isinserted in the box, and then rise as the journal is pressed inward, asufficiency of the bottom being still left open to allow dust or dirt toescape in the usual manner.

Second, I form a box or projecting plate, F,

on the inside of axle-box, and at the end where the journal enters, soas to prevent the lubricant from being splashed out at the joint f. Inold boxes I shall make it of sheet metal, fasten it by screws f f, andin' new ones I preferably cast it with the box. After a careful trial Ifind that it saves no inconsiderable portion of the lubricant, while itavoids the accumulation of oil at the joint, and the consequentgathering thereto of dirt. I

Third, I make an annular recess or groove, a, in axle and near thejournal, for the purpose of receiving an elastic ring, I, that serves toform a packing to prevent the escape of the lubricant, and to excludegrit and dirt from working into the axle-box.

Fourth, I make the piece that is intended to hold the lubricating fabricJ up to the journal of a single longitudinal metallic platespring K, sothat it may be readily bent to accommodate itself to any innerconformation of axle-box, be easily fastened by the screw 70 in front,and be prevented from lateral play by a simple plate or cross-bar, k,which may have turned-up ends. This is not only applicable to old aswell as new boxes, and very efficient for the purpose intended, but iscomparatively cheap and easily adjusted from the bottom by a set-screw,k so as to accommothe lugs 10 k of the spring, so that the fabric willautomatically adjust itself to and bear always along the whole length ofthe journal.

Having thus described my invention, what Iclaim as new is v 1. Thecombination, with axle-box, of a journal-gate, E, having excisions e e,and the guidegroove E, having inclined strips 6 c placed in the lowerend, as and for the purpose set forth.

2. The plate F, projecting inwardly from the rear of axle-box, as andfor the purpose specified.

3. The combination, with an axle having the annular recess or groove to,of the elastic ring I, as and for the purpose set forth.

4. The eombinatiol'l, with axle-box, of a device to hold the lubricatingfabric to the journal, consisting of the plate-spring K, placedlongitudinally on the bottom of the box, fastened at the outer end, andthe cross-bar k as shown and described.

5. The combination, with lubricating fabric J, of the slotted holder Jand guide-plate J as and for the purpose described.

6. The combination, with spring-band K, of a pivoted fabric-holder, J asand for the pur pose specified.
